WARNING
10 min
Both wiring and periodic inspections must be carried out at least 10 minutes
after disconnecting the input power. To remove the front cover, make sure
that the red "DC Link" LED is off. Then remove the metal cover from the
terminals and check the following with a multimeter:
• Voltage between the output busbares U, V, W and the cabinet is
around 0V.
• Voltage between the terminals + HVDC, -HVDC and the cabinet is
below 30VDC.
If you omit this recommendation, you may get an electric shock.
Even though multimeters have their own revisions Schedule, it is convenient
to verify it works properly, specially to check voltage absence. It could be
damaged and show incorrect values. Use a 1.5V battery to verify proper
functioning.
CAUTION
Install the drive on a non-flammable surface. Do not place flammable material
nearby. Otherwise, a fire could occur.
Disconnect the input power if the drive is damaged.
Otherwise, it could result in a secondary accident or fire.
Do not allow lint, paper, wood chips, dust, metallic chips or other foreign matter
into the drive. Otherwise, a fire or accident could occur.
After stopping the drive, some of its parts will stay warm for a while. Wait for the
drive to cool down for handling.
Touching hot parts may result in skin burns.
Do not apply power to a damaged drive or to a drive with parts missing, even if
the installation is complete.
Otherwise, you may get an electric shock.
It is not allowed to weld the cabinet or structure, this could damage the sensitive
electronic components inside the cabinet or structure.

SAFETY INSTRUCTIONS
NOTICE
RECEPTION
The SD750 are carefully tested and perfectly packed before delivering.
In the event of transport damage, please ensure to notify the transport agency and POWER
ELECTRONICS: 902 40 20 70 (International +34 96 136 65 57) or your nearest agent, within 24h from
receiving the goods.
UNPACKING
Make sure model and serial number of the variable speed drive are the same on the box, delivery note
and unit.
Each variable speed drive is delivered with Hardware and Software technical manuals.
RECYCLING
Packaging equipment must be recycled. Separate all different materials (plastic, paper, cardboard,
wood…) and place them in the corresponding containers. Ensure waste collection is properly managed
with a Non-Hazardous Waste Agent.
To guarantee health and natural environmental sources protection, the European Union has
adopted the WEEE directive concerning discarded electric and electronic equipment
(SEEA).
Waste of electrical and electronic equipment (WEEE) must be collected selectively for
proper environmental management.
Our products contain electronic cards, capacitors and other electronic devices that should
be separated when they are no longer functional. These WEEEs should be managed
accordingly with a Hazardous Waste Agent.
Power Electronics promotes good environmental practices and recommends that all its
products sold outside of the European Union, once they reach the end of their life, are
separated and the WEEE managed according to the particular country applicable legislation
(especially: electronic cards, capacitors and other electronic devices).
If you have any questions about the electric and electronic equipment waste, please contact Power
Electronics.
ELECTROMAGNETIC COMPATIBILITY (EMC)
The drive is intended to be used in industrial environment (Second Environment). It achieves compliance
with category C3 defined in IEC/EN 61800-3 standard when the installation recommendations within this
manual are followed. The driver can optionally operate in domestic environments (First Environment),
complying with category C2 defined in IEC / EN 61800-3 standard. For category C1 consult Power
Electronics. Optional IT filter.
Select communication and control system according to the drive EMC environment. Otherwise, systems
could suffer from interferences due to a low EMS level.
CAPACITORS DEPLETION
If the drive has not been operated for a long time, capacitors lose their charging characteristics and are
depleted. To prevent depletion, once a year run the device under no-load conditions during 30-60 minutes.

SAFETY
• Before operating the drive, read this manual thoroughly to gain an understanding of the unit. If
any doubt exists, please contact POWER ELECTRONICS, (902 40 20 70 / +34 96 136 65 57)
or your nearest agent.
▪ Wear safety glasses when operating the drive with power applied or for when the front cover is
removed.
▪ Handle and transport the drive following the recommendations within this manual.
▪ Install the drive according to the instructions within this manual and the local regulations.
▪ Do not place heavy objects on the drive.
▪ Ensure that the drive is mounted vertically and keeping the minimum clearance distances.
▪ Do not drop the drive or subject it to impact.
▪ The SD750 drives contain static sensitive printed circuits boards. Use anti-static safety procedures
when handling these boards.
▪ Avoid installing the drive in conditions that differ from those described in the Environmental Ratings
section.
CONNECTION PRECAUTIONS
▪ To ensure a correct operation of the drive, it is recommended to use a SCREENED CABLE for
the control wiring.
▪ The motor cable should comply with the requirements within this manual. Due to increased
leakage capacitance between conductors, the external ground fault protection threshold value
should be adjusted ad hoc.
▪ Do not disconnect motor cables if the input power supply remains connected.
▪ The internal circuits of the SD750 Series will be damaged if the incoming power is connected and
applied to output terminals (U, V, W).
▪ Do not use power factor correction capacitors banks, surge suppressors, or RFI filters on the
output side of the drive. Doing so may damage these components.
▪ Always check whether the DC Link red LED is OFF before wiring terminals. The capacitors may
hold high-voltage even after the input power is disconnected.
COMMISSIONING
▪ Verify all parameters before operating the drive. Alteration of parameters may be required
depending on application and load.
▪ Always apply voltage and current signals to each terminal that are within the levels indicated in
this manual. Otherwise, damage to the drive may occur.
▪ For correct starting, refer to the start-up section.
HANDLING PRECAUTIONS
▪ When the "Automatic Restart" function is selected, observe the appropriate safety measures to
avoid any damage in case of sudden restart of the motor after an emergency and subsequent
reset.
▪ The "STOP / RESET" key on the driver's own keypad will be operative as long as this option has
been selected. By pressing this button, the drive will not perform an emergency stop. The driver
has a STO function which, installed with an external EMERGENCY pushbutton, will disconnect
the motor power supply and prevent the ability to generate torque in the motor.
▪ If an alarm is reset without having lost the reference signal (setpoint), an automatic start may
occur. Check that the system has not been configured as such. Failure to do so could result in
personal injury.
▪ Do not modify anything inside the driver without the supervision of Power Electronics.
▪ Before starting the parameter setting, reset all parameters.

SAFETY INSTRUCTIONS
EARTH CONNECTION
▪ Ground the drive and adjoining cabinets to ensure a safe operation and to reduce electromagnetic
emission.
▪ Connect the input PE terminal only to the dedicated PE terminal of the drive. Do not use the case,
nor chassis screw for grounding.
▪ Ground the drive chassis through the labelled terminals. Use appropriate conductors to comply
with local regulations. The ground conductor should be connected first and removed last.
▪ Motor ground cable must be connected to the PE output terminal of the drive and not to the
installation’s ground. We recommend that the section of the ground conductor (PE) is equal or
greater than the active conductor (U, V, W).
▪ If the user decides to use screened motor cable, ensure a good 360° connection of the cable
screen in both the drive cabinet and the motor terminal box.

RECEPTION, HANDLING AND TRANSPORTATION
RECEPTION, HANDLING AND
TRANSPORTATION
CAUTION
Read carefully the following installation instructions for a correct mechanical installation.
Otherwise, the equipment can be damaged and lead to personal injury.
Reception and Storage
The SD750 is carefully tested and perfectly packed before delivering. In the event of transport damage,
please ensure that you notify the transport agency and Power Electronics: 902 40 20 70 (International
+34 96 136 65 57) or your nearest agent, within 24h from receipt of the goods.
Make sure model and serial number of the drive are the same on the delivery note and unit.
Drive should be stored in a sun and moisture protected space and with an ambient temperature between
-40°C and +70°C, < 95 RH without condensation. It is recommended not to stack more than two units.
Handling and Transportation
Only the transport methods described in this document or in the delivery notes are permissible. Any other
transport method or system could damage the unit.
SD750 is delivered vertically. Frames 1 and 2 are delivered in a cardboard box. From frame 3 they are
delivered fastened to a wooden pallet. Frames 3 and 4 are covered with a cardboard box and from frames
5 with a wooden box. Depending on the method of transportation, the drive is supllied wrapped to be
protected against dust. Place the entire pallet as close as possible to the installation site before removing
the wooden box to prevent damage to the drive during transportation.
It is mandatory to carry the drive with a pallet truck, a forklift track or a crane, taking into account the load
distribution and its center of gravity. Check the size and weight of the VFD to choose a proper equipment
that can lift a higher weight.
Remove the drive packaging carefully (do not use sharp tools). After removing the packaging, please

This section contains assembly instructions for optimum operation of the inverter and precautions to
avoid personal injury and property damage.
SD750 drives are designed for wall or panel mounting.
The drive may become hot during operation. Install it on a surface that is fire resistant or flame retardant
and with sufficient space around the drive to allow air to circulate. Make sure to follow the space
recommendations given in section 6.3.
Wall mounting drives
The drives SD750 from frame 1 to 4 are are designed for wall mounting. In addition, the frame 4 has
optionally available a plinth that that allows its mounting on the ground..
The installation method and its location must be in accordance with the weight and dimensions of the
drive. Power Electronics recommends hanging the SD750 in a wall or solid structure using the anchors
arranged in the back, which supports the weight and possible forces generated by the wiring..
Use a level to draw a horizontal line on the mounting surface and mark the attachment points. Then,
drill the two holes of the top mounting bolts, and then install the mounting bolts. Do not fully tighten
bolts yet.
Mount the unit with the top two bolts and then fully tighten the mounting bolts. Make sure the SD750 is
flat on the mounting surface.

Cooling
The main heat sources inside the equipment correspond to: losses in the bridge rectifier (IGBTs), the
input filter and the output dV/dt filter. The SD750 series has an overall efficiency higher than 98%, so
losses due to heat dissipation correspond to 2% of the power supplied by the equipment.
The cooling system of the drive depends on its degree of protection and its frame. In general terms, the
drive has been designed with three independent cooling areas.
Cooling airflow for SD750. Frames 4 to 11(Protection Grade IP54).
1st Area - Electronics:
IP20 cabinets incorporate extractors in its upper part that evacuate the internal heat generated in the
area.
IP54 cabinets keep electronic components fully sealed. The internal heat generated is evacuated through
the metal doors thanks to an internal forced convection system.
2
nd
Area – Rectifier bridge, Inverter bridge and DC bus cooling area:
The drive has fans that collect the air from the bottom and evacuate it through the central grid at the top.
The fans propel the air through the radiator thus evacuating the heat generated by the main components.

Topology
The operating principle of the SD750 is the pulse width modulation (PWM). Varying the power supply
voltage and the grid frequency, it is possible to control the speed and torque of the connected induction
three-phase motors thanks to its main components: rectifier bridge, the DC bus, inverter bridge, and
power and control card.
General Block Scheme for frames 5 to 11
The SD750 drive is equipped with an input filter. This input filter significantly reduces the THDi values
and increases line impedance, thus protecting the drive from electrical system distortions. Depending on
the frame, the input filter is connected to the input or to the DC bus. From frames 3 to 11 the filter is
installed in the input side. In frames 1 and 2 the filter is installed on the DC bus (see figure “Power
electronics for Frames 1 and 2 equipment”).
Frames 5 to 11 integrate as standard ultra fast fuses that protect the drive against downstream
overcurrents. Additionally, the drive integrates multiple electrical protections that protect the drive and
the motor, similar to those provided by a motor protection relay.
The SD750 drive includes a power and a control board that are responsible for the rectifier bridge trip,
inverter bridge trip, soft load management, DC bus voltage control and motor operation. In addition, the
control card integrates terminals such as communication ports, digital and analogue inputs and outputs,
colour touch-screen display, alphanumeric display, etc.
The inverter bridge generates the PWM wave that controls the motor response (voltage, current, torque,
etc.). The Power Electronics SD750 series integrates as standard dV/dt filters and a CLAMP system that
reduces significantly the rise time (dV/dt) below 500V/μs - 800V/μs, therefore, it reduces the voltage
peaks in the motor windings, the common mode currents and the EMC emissions.

Power Connection and Wiring
CAUTION
The following installation recommendations are suitable for TN and TT grids. For IT grids refer the
dedicated section. Otherwise, you could cause damage to equipment and personnel.
Wiring and periodic inspections should be performed at least 10 minutes after disconnecting the
input power. When removing the front cover, check that the red DC Link LED is off. Afterwards
you can remove the metal cover and check with a multimeter the following measures:
• The voltage between the output plates U, V, W and the cabinet must be around 0V.
• The voltage between the DC link +, - terminals and the chassis must be below 30Vdc.
Otherwise, you may get an electric shock.
The input and output busbars are labelled according to the following diagram.
Power wiring connection for frames 1 and 2
Power wiring connection for frames 3 to 11
The input terminals L1, L2, L3 and PE (drive power supply), output terminals U, V, W and PE (motor
power supply) must be introduced through the metal plates situated in the bottom part of the cabinet. Do
not drill or mechanize the vents. Otherwise, the drive could reduce its cooling capacity.
The front metal panel corresponds to the motor cables and the rear metal panel to the input cables; these
panels are not delivered neither drilled nor pre-marked to enable any configuration. Each cable must be
equipped with its own cable gland or grommet that prevent dust or moisture from entering the equipment.

POWER CONNECTION
To perform a correct terminals connection, follow the next steps.
▪ Refer to section “Power Terminals” for recommended screws and washers
metrics, as well as recommended torque.
▪ The number of busbars depends on the frame size. Check the “Power
terminals” section.
▪ Before connecting the cables, clean the contact surface with a clean cloth and
ethanol cleaner.
▪ Use a pressure washer and a flat washer between the nut or bolt head and
the terminal lug.
▪ Use copper or aluminium conductors that whithstand a voltage of 600Vac for
equipment with rated voltage up to 500Vac..
The recommended cable types and lengths between the drive (with factory settings) and the motor are:
▪ Unshielded cable: 300m. Asymmetrical 4-wire cable including PE conductor. It is recommended
to use a motor ground cable (PE) with a cross section equal or higher than the supply motor wires
cross section (U, V, W). When single-wire cables are used in three-phase systems, the three
phase conductors must be bundled symmetrically.
▪ Shielded cable: 150m. Symmetrical 3-wire cable with PE conductor- with concentric shield. To
implement an effective shield bonding, an EMC cable gland should be used in both the motor
junction box and the drive cabinet to ensure effective 360º ground connection and a low
impedance path for high frequency current. Refer to “EMC Installation Requeriments” section.

CAUTION
Line voltage (input supply) must never be connected to U, V and W terminals.
Otherwise, the drive will be damaged.
It is absolutely necessary that the installer ensures correct compliance with the laws and
regulations in force in the countries or areas where the drive is to be installed.
Do not use capacitors for power factor correction, surge suppressors or RFI filters on the output
side of the drive. Doing so may damage these components or the drive itself.
All power conductors such as power input cables, output cables to the motor or DC link cables must be
separated from the control, signal, PTC, encoder or data cables. The recommended distances between
the cables are shown in the next figure:
Cable routing distances
Power Electronics recommends that the following cable types are installed in cable racks, trays or in
different wire ducts:
▪ Single-wire signal or data cables with V< 60V
▪ Single-wire cables with 60V<V< 230V
▪ Input power cables with a low level of interferences 230V<V<1000V
▪ Output power cables to the motor and dynamic DC brake with a high level of interference
230V<V<1000V.
▪ Medium voltage cables with V<1000V
Power cables must have a sufficient nominal current to prevent important wiring overheating and voltage
drops. The installer must consider the cable cross-section, cable type, wiring method and ambient
conditions to select the appropriate cable. It is only permitted the use of cooper or aluminium cables.
Please check the maximum cable section and the available holes per phase in section “Power terminals”.

Ground Connection
Before connecting the power conductors, make sure that the chassis of the drive and the adjoining
cabinets are connected to ground through the dedicated (PE) terminals. These are situated at both sides
of the bottom metal walls of the drive and they are labeled with the earth symbol. Check section “Power
Terminals”.
The motor chassis ground must be connected to the drive. In other words, connect the motor’s ground
conductor to the PE protection terminal of the drive and not to the installation’s ground. It is recommended
that the section of the motor ground conductor (PE) has at least the same cross section as the motor
power cables sections (U, V, W). Additionally, it must be installed following the recommendations
indicated in section “Power connection and wiring”.
When connecting the earth, ensure that all connected cable terminals are properely tight and protected
from mechanical forces.
CAUTION
For safety reasons, the earth resistance of the installation must be measured. This must be
established before the first start up of the plant and with the drive disconnected.
It is the responsibility of the installer to provide the appropriate number, type and section of cables
for the ground conductor in accordance with the characteristics of the equipment used and the plant to
minimize ground resistance, which must comply with local and national regulations.

The EMC European Directive defines electromagnetic compatibility as the capability of an apparatus,
an industrial plant, or a system to work satisfactorily in the electromagnetic environment without at the
same time causing electromagnetic disturbances in the apparatus, industrial plant or systems present
in the same environment.
The Electromagnetic Compatibility (EMC) depends on two main characteristics of the equipment:
Electromagnetic Interference (EMI) and Electromagnetic Susceptibility (EMS). The EMC standards
aims to ensure that all the electrical equipment that could operate simultaneously in the same
environment are compatible. This means that the interference immunity of all the devices is greater
than the interference emission of all the devices within the same environment.
The EMC requirements for Power Drive System (PDS) are defined in IEC/EN 61800-3 standard that is
included in the Declaration of conformity CE enclosed. In the European Union, EN61800-3 standard
takes priority over all generic standards. The PDS in the context of this standard comprises the drive
converter, the motor cables and the motor. Therefore, the installer as the ultimate responsible must
follow the installation instructions given within this manual.
Depending on the location of the drive, the standards define four categories distributed in two
environments.
Environments definition
• First Environment: Domestic installations. It also includes premises directly connected to a low-
voltage power supply network without an intermediate transformer which supplies buildings
used for domestic purposes such as shopping malls, cinemas, hospitals…
• Second environment: Industrial installations. Second Environment includes all plants other
than those directly connected to the public low-voltage network which supplies buildings used
for domestic purposes, e.g. factories and those other premises supplied by their own dedicated
transformer.

Notes
[1] “Restricted Installation” means that the installation and commissioning must be carried out by specialist
personnel.
[2] C4 Category applies only for complex systems or when ratings are equal or above to 1000 V or 400 A wich
are unable to comply with the limits of C3 Category. In these cases, C4 Category can be achieved by adjusting
the equipment in situ and applying the EMC recommendations.
SD750 compliance
SD750 variable speed drives have been designed for the industrial use (Second Environment). The
implementation of radio frequency interference filters (RFI filters) and dV/dt filters as standard, and the
correct installation following the recommendations within this manual, permit to achieve compliance
with C3 category defined in IEC/EN 61800-3.
Optionally, the SD750 drive with non-floating earth can be installed in residential areas (First
Environment) by employing optional RFI filters that permit to achieve the C2 category.
The SD750 is not a retail unit. It is neither a plug in device nor a movable device and it is intended to
be installed and commissioned by qualified personnel. Therefore, C1 category will not be required.
The SD750 with floating earth configuration can be installed in industrial (Second Environment) IT
grids. Although it does not integrate RFI filters, following the installation recommendations within this
manual and with its integrated dV/dt filter, it achieves the C3 category defined in IEC/EN61800-3.
Connection
The SD750 do not require the use of shielded motor cable to achieve compliance with C3 category,
when a correct installation is made. Wiring and Installation recommendations are included in sections
“Power Connection and Wiring” and “Ground Connection”.
In shielded cables it is recommended to connect the shield by making 360° contact in both the drive
cabinet and the motor terminal box. As an example, EMC cable glands can be installed as shown in
the next figure.

Correct output motor cables shield bonding
It is recommended to use shielded cable for control signals and to follow recommendations included in
section ”Wiring Recommendations”.
CAUTION
Select communication and control system according to the drive EMC environment. Otherwise,
systems could suffer from interferences due to a low EMS level.
Protections
Short circuit
The SD750 includes from frame 5 to 11 ultra fast input protection fuses as standard. Frame 5 includes
one fuse per phase with a rated current that depends on the drive’s nominal current. From frame 6
upwards, the fuses per phase depend on the number of modules (frame 5) interconnected. The main
characteristics of these fuses are shown in the following table.
However, it is not recommended to install the drive at points where the short-circuit current available is
higher than 200kA. If necessary, install general fuses with a greater breaking capacity and with fastest
overcurrent capacity.

Ground fault protection
The drive is equipped with an internal software that protect the motor and the drive against input and
output unbalanced currents. For further information, see Programming and Software Manual.
This function is not intended to protect people against direct or indirect contacts or against fire, so an
external protection must be provided to ensure that a substantial ground fault current is promptly
interrupted. The SD750 drives are suitable to operate with RCD components Type B, if it is required.
The EMC / EMC filters and motor cable lengths increase the earth leakage currents, so the protection
range is set according to the installation conditions. For additional information, contact Power
Electronics.
Motor thermal protection
The drive includes a motor thermal protection based on the motor performance parameters which
mathematically calculates the remaining heating capacity in the motor. When this reservoir is reduced
below the limits, this is, the motor temperature approaches the maximum, the drive automatically stops
the motor. For further information consult the Software and Programming Manual.
The drive includes as standard a PTC connection that permits monitor the motor temperature. Once
connected and configured, the drive could either stop the motor or generate a warning signal.
Other Protections
Apart from the protections mentioned above, the drive implements additional protections such as
Temporary loss of power, automatic re-start, high and low input and output voltage, overload or
underload of the pump, etc. For further information, consult the Software and Programming Manual.
Safety Stop Function – STO (Safe Torque Off)
The Safety Stop Function allows the drive’s output to be disabled so that the drive cannot provide
power or generate torque in the motor.
The Safe Torque Off function complies with EN ISO 13849-1 PLd and EN 61508 SIL3 (EN60204-1,
stop category 0). This feature is standard and allows you to comply with current safety standards. For
more information see section “STO - Safe Torque Off”.
IT Grids – Floating Earth drives
When planning an IT grid electrical installation select the drive for floating earth operation. Check the
drive reference and make sure that the drive is suitable for this type of installations.
IT grids must be equipped with an insulation monitoring system. To adjust the parameters consider that
the drive has a very high impedance even if there is a large number of equipment working in parallel in
the same IT network.
It is recommended the installation of lightning rods to ground in order to protect against transient
overvoltages. The lightning rod must have a rated voltage greater than the drive rated voltage for the
purpose of preventing its operation during normal conditions.

Note: This table is based on a 100% enable duty (ED). For other ED’s different from 100%, braking
resistors with the same ohmic value shall be used and their power shall be calculated by multiplying
the power of said resistance to 100% (value of the table) by the new ED. Enable Duty means the time
the resistor is working (regeneration). Resistors for 100% of ED = continuous operation. For example,
in case of ED of 30%, it will be multiplied by 0.3.

Wiring Recommendations
Before planning the installation, follow and understand the next recommendations. The parallel cable
routing should be avoid and the distance between the control wiring and the power wiring should be
maximized. It is recommended to route control cables with different voltages in separately cable racks,
trays or ducts.
It is recommended to use shielded cable for all the data, signal or control cables coming from the variable
speed drive. Each cable must have an EMC clip that secures an effective ground shield, making a contact
of the 360º shield.
Shield bonding
Cable shields for digital signal must be grounded at both ends of the cable. It is recommended to use
independent shielded cables for digital and analogue signals. When using multiple analogue signals, do
not use common return for them. If using analogue signals a low-interference is experienced (hum loops),
disconnect the shield grounding from one of the ends. The maximum section for the control cables is
2.5mm² and the recommended tightening torque is 0.4Nm.
Although the control boards are insulated galvanically, for safety reasons it is recommended not to modify
the wiring while the equipment is connected to the input power supply.
CAUTION
Any change to the control board wiring or bridges must be performed following the safety
instructions indicated before. Otherwise, it could cause damage to the equipment and cause damage
to people.

NOTICE
Terminals PIN14 and PIN15 can be used for other functions depending on the invertir bridge
characteristics (frequency regulation by external potentiometer, analogue feedback, etc.). to avoid
multiple connections in one terminal (PIN 14, PIN 15), it is advisable to add external terminals for
supply distribution.
STO - Safe Torque Off
The STO function is defined as: Power, that can cause rotation, is not applied to the motor. The frequency
converter will not provide energy to the motor, which can generate torque.
For three-phase asynchronous motor, that means to stop three-phase power supply to the stator.
This function corresponds to a Category 0 Emergency Stop according to IEC 60204-1. When the drive
is running and the STO function is applied, the motor will freely stop by its own inertia.
The STO function integrated as standard in the SD750 permits to achieve safety level SIL3 (PLe) for the
safe stop function. SIL3 requires the use of an emergency pushbutton The maximum reaction time of
STO function is less than 50ms. See section “Safety Integrity Level SIL3-PLe” for additional information.
By using this function you can safely carry out cleaning, maintenance or emergency work on non-electric
parts of the equipment, without having to disconnect the power supply. In case STO safety function is
not used, user must connect the corresponding terminals.
Based on a study of each application and risk assessment, the designer should define the required safety
function and safety level.
CAUTION
The STO safety function does not disconnect nor the main neither the auxiliary power supply.
With STO function the drive disconnects the motor power supply. To carry out electrical
maintenance tasks, isolate the inverter. Particular care must be taken with the active conductors
inside the inverter. Failure to do so could result in damage to equipment and personnel.
Do not use the STO function as a normal drive stop.

CONTROL CONNECTION
Safety Integrity Level SIL3- PLe
This configuration provides a highly reliable safety level. When the sensor is activated due to an
emergency situation, the STO function interrupts the power supply to the motor. The motor will stop for
its own inertia or will prevent an accidentally start.
The sensors (emergency push buttons, limit switches, etc.) must be certified as safety elements.
The value of the average probability of a dangerous failure per hour (PFH) of all elements applicable
to the safety function, must not exceed the limit of the corresponding SIL level. The installation must
be performed by trained personal with experience in functional safety.
Example 1: Safety function with automatic restart by emergency stop buttons (SIL3, PLe). It is
mandatory that the stop button has 2 closed contacts (NC) that will be connected to the safety inputs
of the relay.
Example 1- Emergency stop push button
CAUTION
According to EN 60204-1 automatic restart is not allowed after an emergency stop. For this reason
the machine control must prevent an automatic start after an emergency stop.
For SIL 3 applications the safety function has to be tested regularly (approximately once per
month) in order to detect certain failures.

Example 2: SIL3 (PLe) Safety door opening for maintenance tasks with manual restart. This
function is used to prevent an unexpected restart when a maintenance task is being carried out in a

CAUTION
For SIL 3 applications the safety function has to be tested regularly (approximately once per
month) in order to detect anomalies or possible failures.
According to EN 60204-1 automatic restart is not allowed after an emergency stop. For this reason
the machine control must prevent an automatic start after an emergency stop.

CONTROL CONNECTION
Connection with ATEX motors
The ATEX standard is related to the use of machinery, installations and equipment in areas with a
potentially explosive atmosphere. In the European Union, the use of equipment in these areas Is
regulated by two complementary directives: Directive 1999/92/EC for the installation environment and
worker’s protection, and Directive 94/9/EC for the ATEX equipment. These guidelines and directives are
based on two basic concepts: the classification of potentially explosive areas or zones and the limitation
of equipment that can be installed in each of them.
Power Electronics provides a solution for driving ATEX motors such as “Ex nA”, “Ex d” and “Ex p” under
the ATEX zone areas illustrated below. For different motor and ATEX zone combinations, consult Power
Electronics.

CONTROL CONNECTION

EN
As shown in the figure above, the SD750 drive and the ATEX relay must be installed in a safe zone,
outside the ATEX zone. This solution is valid for motors with "Ex d" or "Ex p" protection installed in zones
1 and 2, or motors with "EX nA" protection installed in zone 2. The external relay must be certified for
ATEX zones and Must be compatible with the following features: 24 Vdc power supply voltage, 2 safety
inputs, at least 2 open contacts and reset function. (Exemple: ZIEHL - PTC MSR 220Vi).
The SD750 series features a dV/dt filter and a unique CLAMP system that reduces dV/dt and voltage
peaks in the motor windings. This reduces the risk of sparks in the windings, motor overheating and
leakage currents through the bearings. In addition, it is possible to regulate the thermal protection of the
motor, thus increasing the protection against overheating in the motor. In self-ventilated motors, the
inverter may require an oversizing according to the derating curves provided by the motor manufacturer.

MODBUS COMMUNICATION
MODBUS COMMUNICATION
Introduction
To guarantee a correct operation of the drive, peripheral elements must be correctly selected and
properly connected. A wrong installation and/or application could cause a wrong operation of the system
or a reduction of the long life of the equipment, as well as damage to the components. This manual
should be read and understood carefully before proceeding.
The purpose of the Serial Communication Bus of the SD750 drive is to integrate the drive itself into a
network compatible with the Modbus communications protocol. This is possible using the physical
communications ports RS485, Ethernet or USB port.
The Modbus communications system allows the SD750 drive to be controlled and / or monitored as a
slave by a Modbus master from a remote location.
The RS485 network allows to connect up to 240 computers on the same network.
The SD750 drive operates as a peripheral slave when connected to a Modbus system. This means that
the drive does not initiate the communication task, the master will start the task instead.
Virtually all of the drive operating modes, parameters and drive characteristics are accessible through
serial communications. As an example, the master can give command to start and stop the drive, check
the status of the SD750, read the current consumed by the motor, etc. The master mode can access all
the possibilities of the drive.

MAINTENANCE
MAINTENANCE
The SD750 Series drives are industrial electronic products that contain advanced semiconductor elements.
For this reason, temperature, humidity, vibrations and worn components can affect performance. To avoid
any possible irregularities, it is recommended to carry out periodic inspections.
Warnings
Make sure to disconnect the drive from the power supply while performing maintenance.
Make sure to check that the DC bus voltage has been fully discharged before servicing. The voltage
between the bus terminals (+ HVDC and -HVDC) must be less than 30Vdc. Note that the DC bus
capacitors of the electronic circuit may remain charged even if the mains supply is disconnected.
The correct output voltage of the drive can only be measured by using an RMS voltage meter. Others
voltage meters, including digital voltage meters, would give incorrect readings due to the high switching
of the frequency PWM.
Routine Inspection
Make sure to check the following points before handling the drive:
• Installation site conditions.
• Drive cooling system conditions.
• Excessive vibrations in the motor.
• Excessive overheating.
• Normal output current value on the monitor.

Dynamic Braking Unit B150
The Dynamic brake permits to control the regenerated energy for series SD750 (integrated in frames 1
and 2). B150 dynamic brake activates an IGBT to discharge the DC bus with external resistors when
the DC voltage overpasses a pre-set value. This activation signal can also be sent by the drive in slave
mode from the common fiber optic port included in the control board.
The B150, with reduced dimensions and high reliability, is the main power-switching device of such
dynamic braking systems.
